TRAVELING VALVE.

Application filed April 15,

This invention relates to improvements in traveling valves for use in oil wells and the like, and has for its principal object to provide a valve which is of such construction as i to relieve the pressure which must necessarily accumulate below the valve of the type used in the present construction of traveling valves in order to unseat the valve and permit the fluid to pass upwardly through the same.

Another important object of the invention is to provide a traveling valve which includes a protector sleeve, whereby the parts will be protected against breakage and disvalve.

Another important object of the invention is to provide a traveling valve of the above mentioned character which is simple in construction, inexpensive, strong, and durable, and further well adapted to the purpose for which it is designed.

Other objects and advantages ofthe invention will become apparent when taken in connection with the accompanying drawing.

In the accompanying drawing forming a part of this application, and in which like numerals designate like parts throughout the same:

Figure 1 is a vertical sectional View through the traveling valve embodying my invention. This sleeve furthermore provides a guide means for holding the rings and the cups in contracted positions so that p the same may be inserted to proper position. When the guide sleeve is shoved downwardly, it will compress all the rings and cups and roll the same in proper working position. This protector sleeve will move rigidly with the traveling valve.

Figure 2 is a transverse section taken approximately on line 22 of Figure 1, and

Figure 3 is a bottom plan view of the valve seat.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, designates generally my improved valve the same comprising the chamber 2. A tubular extension 3 is formed on the bottom of this chamber and affords means whereby a communication may be had with the fluid delivery pipe extending vertically in the well (not shown). The upper portion of this chamber is internally threaded and an annular shoulder a is formed on the inner wall the numeral 1 1926. Serial No. 102,217.

of the chamber at a point below the threaded upper end thereof and the-purpose of this shoulder will be hereinafter more fully described.

T'he usual leather cups which are associated with traveling valves are supported on the tubular extension 3 in the manner well known in the art, and these cups are designated generally by the numeral 5.

The traveling valve further includes the cage 6, the same having its lower portion externally threaded for threaded engagement with the internally threaded upper end of the chamber 2 as indicated at 7. A series of outlet ports 8 are formedin the sides of the age 6 and the top 9 of the cage is provided with a central enlarged opening 10, the purpose of which will also hereinafter be more fully describet.

r1 ring-like valve seat 11 is provided with an annular flange 12 on its peripheral face, and this flange is adapted to-be secured be tween the upper face of the annular shoulder 4 formedon the inner wall of the chamher 2 and the lower edge of the cage 6 in the manner clearly shown in Figure 1 whereby the ring 11 is securely held in proper posi tion. The inner edge portion ofthe ring 11 is beveled to provide the substantially conical shaped seat 13.

Adapted for cooperation with the conical valve seat 13 is the ball valve 14, the same being adapted for downward and upward movement within the chamber 2. This ball valve 1 1 is carried on the lower'end of the valve stem 15, the latter extending upwardly through the cage 6 and being threaded at its upper end in the lower end of the coupling 16, the upper end of which is threaded into the lower end of the actuating rod 17 This coupling 16 is provided with the enlarged conical shaped portion 18 thereon which is adapted to seat on top of the cage 9, the lower portion of the coupling being adapted to extend downwardly into the cagethrough the opening 10. The opening is of a diameter greater than the diameter of the valve stem and this construction is adapted to provide a means whereby the valve stem'and the ball valve carried onthe lower end thereof may readily and easily adjust or plumb itself in the barrel.

A protector sleeve 19 is fitted over the valve and the top of this sleeve is arovide-d with the openin to permit the sliding lit) movement of the coupling 16 therethrough. This sleeve vvil protect the valve while in operation so that there will be no possibility of any of the parts of the valve becoming broken or otherwise causing injury being sustained by the cups as would cause a leakage to occur.

The protector sleeve 19 is adapted to rest on the top of the barrel (not shown) and is stationary while the valve travels vertically therethrough. The sleeve will protect the valve while in operation as well as the rods in the well from burrs or any other obstructions which may lie in the tubing that would cause the cups to be cut and thus cause them to leak. The sleeve will turthern'iore insure uniformity in making cups up on the valve after the cups have been properly positioned.

The sleeve 19 will not however interfere with the operation of the traveling-valve when in use.

The protector sleeve 15) is adapted to rest on the top of the working barrel when the latter is in operation. The inner diameter of the protector sleeve i9 is substantially the same as the inner diameter of the worl s ing barrel. This sleeve will protect the cups when the valve is traveling through the pipes before it reaches the pump barrel in the process of placing the valve in the well. When the valve reaches the top of the pumping barrel, the sleeve 19 being of the same inner diameter as the barrel will strike the top of the barrel and cannot move downwardly any further. This. will permit the valve to move dowmvardly into the working barrel.

As soon as the traveling valve strikes the fluid on the downward strol-te, the body of" the valve stops and by the ball being attached to the lower end of the valve stem 15 which is carried by the actuating rod, the weight of the rod will force the ball downwa dly so as to become unseated from the seat 13- and thereby allow the i'luid to pass upwa rely through the valve.

'lfliis construct on will obviate the necessity of having to accumulate pressure below the valve as must now be done with the types of v lves now in use tor unscating the same in order to pern'iit the tiuid. to pass upwardly therethrougl-i.

The simplicity in which my improved traveling valve constructed, enables the parts to be readily as "emblcd or disassemble 1 at all. times be l, and furthermore \Vlli tive and efiicien-t in its operation.

hile I have shownthe preferred embodiment otthe invention it is to be understood tl minor changes in the size, shape, and arrangement of parts may be resorted to without de imrting from the spirit of the invention, and the scope of the claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. A traveling valve of the class described comprising a cylindrical chamber, a fluid supply pipe associated with the bottom thereof, an annular shoulder formed on the inner wall of the chamber adjacent the top thereof, a cage having its lower end threaded into the top of the chamber, said cage being provided with a series of outlet ports, a ring-like valve seat clamped between the upper face of said shoulder and the bottom edge of Said cage, a reciprocating valve stem extending vertically through the cage and into said chamber, and a be 1 valve arranged on the lower end of the stem and operable within said chamber, said ball valve adapted to normally seat against the bottom of said valve seat.

2. A traveling valve of the class described comprising a cylindrical chamber, a fluid supply pipe associated with the bottom thereof, an annularshoulder tormedon the inner wall of the chamber adjacenflthe top thereof, a cage having its lower end threaded into the top of the chamber, said cage being provided with a series of outlet ports, a ring like ralve seat clamped between the upper tare oi said shoulder and the bottom edge of said cage, a. reciprocating valve stem extending vertically through the cage and into said chamber, a ball valve arranged on the lower end of the stem and operable within said chamber, said ball valve adapted to normally seat against the bottom of said valve seat, and a protector sleeve Si-irrounding the valve.

A traveling valve comprising a cylindrical chamber, a fluid supply pipe associated with. the bottom thereof, an annular shoulder formed on the inner wall of the appended chamber adjacent the upper end thereof, a
